Volume Dispenser
What is Volumetric Dispensing?
Volumetric dispensing is a dispensing process in which exactly defined adhesive quantities are applied through precise volume control. Unlike time-controlled dispensing, volume dispensers consistently deliver reproducible results regardless of viscosity fluctuations or pressure changes.
Properties of Volumetric Dispensing
- Exact volume control independent of material viscosity and system pressure
- Highest repeatability with typical volume errors below ± 1 %
- Compensation of temperature-induced viscosity fluctuations without process adjustment
- Suitable for 1K and 2K adhesive systems of varying viscosity
- Integratable process monitoring for complete quality documentation
- High cycle rates for use in fully automated production lines
Applications
- Electronics manufacturing: Precise potting of defined volumes in assemblies
- Semiconductor technology: Exact adhesive quantities for die attach processes
- Optics: Reproducible micro-droplets for lens and sensor bonding
- Medical technology: Validatable dispensing processes for regulated manufacturing environments
- Automotive: Uniform adhesive distribution in structural series bonding
Processing Guidelines
- Gear dispensers are particularly suitable for low-viscosity materials with highest precision requirements
- Screw and piston dispensers are suitable for high-viscosity pastes and masses
- For reactive 2K systems, actively monitor pot life during the process
- Jet valves complement volumetric systems for contactless microdispensing
- Regular gravimetric calibration ensures long-term system accuracy
